Understanding the interfacial interaction mechanisms between oil and minerals is of vital importance in the applications of petroleum production and environmental protection. In this work, the interactions of dodecane with mica and calcite in aqueous media were investigated by using the drop probe technique based on atomic force microscopy. For the dodecane-mica interactions, the electrical double layer (EDL) repulsion dominated in 10 mM NaCl solution, and a higher pH facilitated the detachment of dodecane.

Exciton emitters in two-dimensional monolayer transition-metal dichalcogenides (TMDs) provide a boulevard for the emerging optoelectronic field, ranging from miniaturized light-emitting diodes to quantum emitters and optical communications. However, the low quantum efficiency from limited light-matter interactions and harmful substrate effects seriously hinders their applications. In this work, we achieve a ∼438-fold exciton photoluminescence enhancement by constructing a Fabry-Pérot cavity consisting of monolayer WS and a micron-scale hole on the SiO/Si substrate.

Porcine deltacoronavirus (PDCoV), also known as HKU15, is a swine enteropathogenic virus that is believed to have originated in birds. PDCoV belongs to the genus Deltacoronavirus (DCoV), the members of which have mostly been identified in diverse avian species. We recently reported that chicken or porcine aminopeptidase N (APN), the major cellular receptor for PDCoV, can mediate cellular entry via three pseudotyped retroviruses displaying spike proteins from three avian DCoVs (HKU11, HKU13, and HKU17).

Influence of drought stress on phosphorus dynamics and maize growth in tropical ecosystems.

BMC Plant Biol

January 2025

Center for Eco-Environment Restoration of Hainan Province, School of Ecology, Hainan University, Haikou, 570228, China.

Drought has a significant impact on ecosystem functions, especially on the biogeochemical cycling of phosphorus (P), which is a crucial nutrient for plant growth and productivity. Despite its importance, the effects of different drought scenarios on soil P cycling and availability remain poorly understood in previous studies. This study simulated drought conditions in tropical soils using maize as a test crop under varying field capacity (FC) levels (100%, 80%, 60%, 40%, and 20%) over a 60-day pot experiment.

Background: Drug response prediction is critical in precision medicine to determine the most effective and safe treatments for individual patients. Traditional prediction methods relying on demographic and genetic data often fall short in accuracy and robustness. Recent graph-based models, while promising, frequently neglect the critical role of atomic interactions and fail to integrate drug fingerprints with SMILES for comprehensive molecular graph construction.

Despite considerable research underscoring the importance of carbohydrate intake in relation to the risk of type 2 diabetes (T2D), a comprehensive assessment of this relationship is currently lacking. We aimed to examine the associations of various types and food sources of dietary carbohydrate intake with the risk of T2D, to evaluate potential effect modification by other factors, including genetic susceptibility, and to explore the potential mediators for such associations. The present study included 161,872 participants of the UK Biobank who were free of prevalent cancer, cardiovascular disease, or diabetes, and had at least one validated 24-h dietary recall assessment.

Bacterial indole-3-propionic acid inhibits macrophage IL-1β production through targeting methionine metabolism.

Sci China Life Sci

January 2025

State Key Laboratory of Livestock and Poultry Breeding, College of Animal Science, South China Agricultural University, Guangzhou, 510642, China.

The gut microbiota plays key roles in host health by shaping the host immune responses through their metabolites, like indole derivatives from tryptophan. However, the direct role of these indole derivatives in macrophage fate decision and the underlying mechanism remains unknown. Here, we found that bacterial indole-3-propionic acid (IPA) downregulates interleukin-1beta (IL-1β) production in M1 macrophages through inhibition of nuclear factor-kappa B (NF-κB) signaling.

Department of Spine Surgery, Honghui Hospital, Xi'an Jiaotong University, No.555 Friendship East Road, South Gate, Beilin District, Xi'an, 710054, Shaanxi, China.

This study delved into the molecular mechanisms underlying mechanical stress-induced intervertebral disc degeneration (msi-IDD) through single-cell and high-throughput transcriptome sequencing in mouse models and patient samples. Results exhibited an upsurge in macrophage presence in msi-IDD intervertebral disc (IVD) tissues, with secreted phosphoprotein 1 (SPP1) identified as a pivotal driver exacerbating degeneration via the protein kinase RNA-like endoplasmic reticulum kinase/ activating transcription factor 4/ interleukin-10 (PERK/ATF4/IL-10) signaling axis. Inhibition of SPP1 demonstrated promising outcomes in mitigating msi-IDD progression in both in vitro and in vivo models.
